[0040] Such as figure 1 Shown is a schematic top view of the data leads of the array substrate according to the embodiment of the present invention. The array substrate of this embodiment mainly includes a plurality of data leads parallel to each other located in the non-display area. In this embodiment, the data leads are arranged sequentially in columns. Specifically, the data leads are located in the wiring area in the non-display area. Each data wire includes multiple segments of first wires 101 and multiple segments of second wires 102 . Multiple segments of first lead wires 101 are disposed on the first metal layer and arranged at intervals. Multiple segments of second lead wires 102 are disposed on the second metal layer and arranged at intervals. A first insulating layer having a first via hole 103 is disposed between the first metal layer and the second metal layer ( figure 1 not shown). The first lead 101 and the second lead 102 belonging to the same data lead ...

[0055] Such as Image 6 As shown, it is a schematic flow chart of the manufacturing process of the data leads of the array substrate according to the embodiment of the present invention. The manufacturing process may include the following steps S610 to S670.
[0056] In step S610, the first metal layer is formed as figure 2 The multiple first lead wires 101 arranged at intervals are shown;
[0057] Such as figure 2 As shown, the first leads 101 are located on the first metal layer and arranged at intervals. The first leads 101 include first leads 101 in odd columns and first leads 101 in even columns. Multiple segments of first wires 101 in odd columns of data wires are distributed in odd rows of the data wires to which they belong, and multiple segments of first wires 101 in even columns of data wires are distributed in even rows of data wires to which they belong. Specifically, the multiple segments of first leads 101 in the odd-numbered columns of data leads are sequ...

[0073] This embodiment is a further optimization of the shape and material of the data leads in the first and second embodiments.
[0074] In this embodiment, the first leads 101 of each data lead are parallel to each other, the second leads 102 of each data lead are parallel to each other, and the first lead 101 and the second lead 102 have the same line width.
[0075] Since the first lead 101 and the second lead 102 constituting each data lead have the same line width, the overall line width of each data lead remains uniform.
[0076] In this embodiment, the materials of the first lead 101 and the second lead 102 are copper, aluminum and molybdenum. Alternatively, the material of the first lead 101 and the second lead 102 is an alloy made of two or three of copper, aluminum and molybdenum.
[0077] In this embodiment, the material of the pixel electrode layer 204 is any one of the following materials: indium tin oxide, indium zinc oxide and tin oxide.
